Using a Rotary Position Sensor
Posted: Fri Nov 16, 2012 8:58 am
I found these while poking around Digikey:
http://www.digikey.com/product-detail/e ... ND/2080232
It is called a rotary position sensor, and the data sheet (http://www.bourns.com/data/global/pdfs/3382.pdf) says it is used for things like dishwasher controls and audio controls.
Can you put it on a shaft and have a really cheap ($2.52) absolute rotation measurement device? It looks like it is identical to a rotary potentiometer. Most rotary pots are only rated for 10K cycles, but this thing says it is good for 1M.
Has anyone ever used these, and is there a catch? Because it seems to me like it is much better than a much more expensive rotary pot or a rotary encoder.
Thanks.
